Definitions

  • the invention concerns the technical sector relating to automatic machines, and more precisely to automatic packaging machines.
  • the invention concerns a device for feeding sheets in sequence in a lying configuration to a device for folding said sheets, each of which consists, for example of an information sheet of a drug, to allow it to be inserted into a corresponding box, together with the relative drug.
  • folding apparatuses that have one or more folding seatings disposed in sequence on a folding path, which allow to make folds in sequential steps, in order to obtain sheets folded in a Z or double Z, or other similar shapes, usually rather complex.
  • a more recent folding apparatus described in the PCT International Patent Application published under n. WO2017068178, in the name of IMA Industria Macchine Automatiche, comprises, like other previous apparatuses: a conditioning unit, intended to prepare each sheet for folding; a folding unit disposed downstream of the conditioning unit, intended to receive the sheet in a flat configuration and fold it into a tubular configuration; and an extractor unit, to pick up the sheet from the folding unit and direct it toward a pair of counter- rotating rollers belonging to the folding unit, which provide to compress the tube and transport it outside the folding apparatus.
  • a sheet to be folded is fed through an entrance guide to a substantially cylindrical conditioning seating, made in a containing body, in which there is a winding shaft, coaxial thereto.
  • the latter has a longitudinal slit in which the arriving sheet is inserted.
  • a controlled rotation of the winding shaft forces the sheet to assume a circular configuration inside the conditioning seating.
  • the extractor unit comprises an extractor element mobile longitudinally with respect to the conditioning seating and driven by a belt transport, which slides along a groove made in the folding shaft and engages the sheet in a tubular configuration.
  • the extractor element is made to translate toward the counter- rotating rollers of the folding unit and transports the sheet, removing it from the folding shaft, until the sheet itself engages the counter-rotating rollers and is drawn by them.
  • the maximum operating speed, and therefore the productivity of the machine are conditioned by the fact that at least the folding shaft functions according to a start-stop principle, since it has to stop in order to receive the sheet, rotate to wrap it in a tube, and then stop again until the extractor element has completed its travel so as to take the tube as far as the folding unit.
  • Document US 4,221,373 is also known, which describes an apparatus for folding sheets of paper or suchlike, which comprises a store where the sheets are stacked, a feed mechanism which includes one or more suction heads in order to remove sheets in succession from the bottom of the pile of the store, a drum transporter, rotating around a fixed horizontal axis, on the periphery of which there are grippers able to open when the one or more suction heads deliver an initial portion of a sheet, and then to close over it in order to remove the sheet from the store and which winds around the periphery of the rotary drum transporter.
  • the latter carries the sheet removed toward a closed belt-type conveyor, downstream of the rotating drum transporter, which conveys the sheet to a folding unit.
  • Purpose of the present invention is therefore to propose a device for picking up and feeding sheets, for example, information sheets of a drug or a cosmetic product, to a device for folding said sheets, able to carry out the operations of picking up and feeding the sheet continuously, without it being necessary to stop and restart any component.
  • Another purpose of the invention is to provide a folding device which allows to obtain an adjustment of the calibrations necessary to obtain the removal of a single sheet in a simple and rapid manner, according to the characteristics of the sheet itself.
  • Another purpose of the invention is to propose a folding device which is simple to manufacture, with minimum requirements for calibration and maintenance, and low cost.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • the purposes described above are fully achieved by means of a device provided to feed sheets, in a lying configuration and in sequence, to a device for folding the sheets of paper or similar materials comprising a belt-type conveyor mobile according to a direction of feed of the sheets to be folded.
  • the feed and folding devices both belong to a feed and folding apparatus for sheets to a packaging machine.
  • the feed and folding apparatus comprises a store of sheets stacked in a pile.
  • the feed device is disposed upstream of the folding device with respect to the direction of feed of the sheets to be folded.
  • the feed device comprises: separator members, intended to separate the external portion of the sheet to be removed from the base of the pile, and pick-up members, operating in a suitable phase relation with the separator members, configured to take the external portion into contact with the belt-type conveyor at the entrance to the folding device.
  • the separator members are mobile between a distanced position, in which they do not interfere with the sheet, and a close-up position, in which they are in proximity to the external portion.
  • the separator members are also provided with suction means, intended to create a depression in correspondence with the external portion in order to attract it into contact with the separator members so as to detach it from the base of the pile.
  • FIG. 1 schematically shows a lateral view of the main members of the folding device which is the object of the invention, in a preferred embodiment
  • - fig. 2 schematically shows a front view of the device in fig. 1 ;
  • - figs. 3, 4 and 5 schematically show the same view of the folding device shown in fig. 1, in subsequent operating steps of picking up and folding a sheet.
  • the reference number 100 is used to indicate an apparatus for feeding and folding a sheet 1 of paper or similar material, for example a prospectus illustrating a package for a drug, a cosmetic product or other.
  • the apparatus 100 is intended to operate at the service of an automatic packaging machine to pick up sheets 1 in sequence in a lying configuration from a store 2, in which the sheets 1 are stacked in a pile la, to fold them in a predetermined folding pattern, and then to forward them to the packaging machine, in which suitable means for picking up the folded sheet and inserting it into a corresponding package, together with the product to be packaged, are conveniently provided.
  • the feeding and folding apparatus 100 comprises a device 50 for feeding sheets 1 in sequence, disposed in proximity to the store 2 and intended to pick up single sheets 1 from the base of the pile la, and a folding device 10 which is the object of the invention, disposed downstream of the feed device 50 with respect to a direction of feed of the sheets 1 to be folded indicated with an arrow W in the drawings cited.
  • the folding device 10 comprises and is based on a closed circuit belt-type conveyor 11, mobile in said direction of feed W.
  • the conveyor 1 covers an operating path which extends (see fig. 1) between a zone A for picking up a sheet 1 in a lying configuration, in proximity to the feed device 50, and a zone E for expelling it in a folded configuration. Subsequently, the conveyor 11 travels a return path, inoperative, between the expulsion zone E and the pick-up zone A.
  • the sheets 1 are transported in the folding device 10 resting on an active upper face 1 1a of the conveyor 11, suitably supported and guided along the operating path, as will be described in more detail below.
  • the conveyor 1 1 is preferably but not restrictively made with a strip of yielding and inelastic elastomer material, of any type available on the market, and provided with suitable mechanical characteristics.
  • the conveyor 11 is supported by a first routing roller 12, mounted transverse to the direction of feed W, rotatable idly around its axis or motorized independently, depending on particular construction requirements.
  • the folding device provides a winding unit 13, intended to pick up each sheet 1 from the conveyor 11 and wind it in a tubular configuration.
  • the winding unit 13 comprises a fixed element 16 and a mobile element 17 mounted adjacent to each other.
  • the fixed element 16 is provided with a curvilinear section 16a, forming a sort of tube portion, and with a linear section 16b, which extends upstream with respect to the direction of feed W.
  • the latter also has, at its end most upstream, a flap 16c which extends toward the conveyor 11, to constitute a guide for the sheet 1 arriving along the operating path.
  • the mobile element 17, in turn, consists of a curvilinear section 17a, which in turn forms a sort of tube portion, and of a linear section 17b, connected to alternative drive means of a substantially known type.
  • the curvilinear section 17a faces the curvilinear section 16a of the fixed element 16 and has an opposite concavity, so as to form a winding seating 14 intended to receive the sheet 1 to take it into a tubular configuration.
  • the two curvilinear portions 16a, 17a, and at least the parts of the corresponding linear portions 16b, 17b in proximity to them, are also shaped like a comb, so as to alternate a series of apertures, parallel to each other, the function of which will become evident hereafter in the description.
  • the lower ends of the curvilinear sections 16a and 17a are distanced from each other, so as to form a slit 15 transverse with respect to the feed of the conveyor 11, disposed in proximity to the active face 11a thereof.
  • the mobile element 17 can be driven in translation between an advanced winding position V (fig. 1), and a retracted exit position U (fig. 5), by drive means of a known type, to widen the slit 15 and facilitate the exit of the sheet 1 in a folded configuration.
  • the winding unit 13 also comprises a lead-in roller 18, idle around its axis, disposed in correspondence with the slit 15, on the opposite face of the conveyor 11.
  • the lead-in roller 18 is intended to facilitate the entry of the sheet 1 into the winding seating 14.
  • Another motorized accompanying roller 19 is provided in the winding unit 13 in proximity to the winding seating 14, on the opposite side with respect to that of the slit 15, to facilitate the winding of the sheet 1 into a tube once it has entered the winding seating 14.
  • the accompanying roller is made (see fig. 2) with a plurality of segments 19a, mounted in such a way that their outermost portion is slightly inserted into the winding seating 14, through the corresponding apertures made in the curvilinear sections 16a and 17a.
  • the accompanying roller 19 is mounted mobile with respect to the winding seating 14, and in particular with respect to the fixed element 16. To this purpose, it comprises known repositioning means, intended to allow it to be fed or retracted with respect to the axis of the winding seating 14. In this way the accompanying roller 14 allows to wind the sheets 1 to be folded into a tube with a different diameter. This characteristic is necessary and must be provided in order to vary the width of the sheets 1 in the folded configuration, depending on the width required for the subsequent insertion of the sheets 1 in the relative package.
  • the folding device 10 also comprises a folding unit 20, mounted in proximity to the winding unit 13 and intended to act on the sheet 1 in its tubular configuration, inside the winding seating 14, to compress it until it is taken to its flattened configuration, and then to convey it out of the winding seating 14 toward the belt- type conveyor 1 1.
  • the folding unit 20 comprises (fig. 1) a drive roller 21, mounted immediately downstream of the winding unit 13, in proximity to the curvilinear section 17a of the mobile element 17.
  • the drive roller 21 consists (see also fig. 2) of a plurality of equidistant small drive rollers 21a, which in turn are mounted on a shaft 21b to which drive members (not shown) are connected.
  • the shaft 21b is driven by motor members (not shown), to rotate around its axis, by a predefined and adjustable angle, according to alternating directions of rotation.
  • the folding unit 20 also comprises folding means 22, consisting of a plurality of folding rollers 22a, mounted on corresponding cams 23, each one attached to a corresponding small drive roller 21 a.
  • the folding rollers 22a can oscillate, around the axis of the shaft 21b, as a consequence of the rotations of the latter, between an inactive position R (fig. 1) and a folding position P (fig. 5), and are intended to be inserted, in the path toward the folding position P, inside the winding seating 14, in order to compress the sheet 1 into a tubular configuration and facilitate its exit from the winding seating 14.
  • the folding device 10 comprises ejector means 30, disposed downstream of the winding unit 13 and of the folding unit 20 described above, with respect to the direction of feed W, in correspondence with the ejection zone E, and intended to remove from the conveyor 11 the sheet 1 in its folded configuration and expel it from the folding device 10, to deliver it to successive pick-up devices of the packaging machine, not shown.
  • the ejector means 30 comprise a pair of counter-rotating motorized rollers, respectively first 31 and second 32.
  • the first 31 and second 32 ejector rollers are disposed on opposite sides with respect to the conveyor 1 1, with the respective facing surfaces in contact with it. In this way, a sheet 1 coming from the winding unit 13 and the folding unit 20, and disposed resting on the conveyor 1 1, is pressed by the pair of ejector rollers 31, 32 and further flattened before being expelled from the folding device 10.
  • the latter also comprises other secondary components, and in particular: a motor roller 40, in turn driven by its own motor members (not shown), which in the embodiment shown is disposed in the lower part of the folding device 10, which engages the conveyor 11 and causes it to move; a tensioning roller 41, disposed between the drive roller 40 and the routing roller 12, which in turn engages the conveyor 1 1 to define its tension; and a second routing roller 42, disposed immediately upstream of the slit 15, and downstream of the flap 16c of the fixed element 16, to help the sheet 1 to advance along the operating path.
  • a motor roller 40 in turn driven by its own motor members (not shown), which in the embodiment shown is disposed in the lower part of the folding device 10, which engages the conveyor 11 and causes it to move
  • a tensioning roller 41 disposed between the drive roller 40 and the routing roller 12, which in turn engages the conveyor 1 1 to define its tension
  • a second routing roller 42 disposed immediately upstream of the slit 15, and downstream of the flap 16c of the fixed element 16, to help the sheet 1 to advance along
  • the feed device 50 comprises separator members 60, intended to separate from the base of the pile la the external portion lb of the sheet 1 to be removed (fig. 3), and pick-up members 70, intended to take the external portion lb toward the conveyor 11 of the folding device 10, in particular, configured to take the external portion lb of the sheet 1 into contact with the belt-type conveyor 1 1 at the entrance of the folding device 10.
  • the pick-up members 70 are mobile, in particular in rotation, to be taken, when the separator members 60 are in the distanced position D, into the space between the flap of the external portion lb of the sheet 1 and the rest of the pile la, increasing its separation.
  • the separator members 60 comprise a pair of gripping rollers 61, 62, parallel to each other and mounted on the same shaft, on which a suction block 65 is also mounted integral, provided with means, in particular a pair of suction channels 66, which lead to the upper face 67 of the suction block 65.
